-NEWS for rsync 2.6.4 (30 March 2005)
-Protocol: 29 (changed)
-Changes since 2.6.3:
+NEWS for rsync 2.6.5 (UNRELEASED)
+Protocol: 29 (unchanged)
+Changes since 2.6.4:
- OUTPUT CHANGES:
-
- - When rsync deletes a directory and outputs a verbose message about
- it, it now appends a trailing slash to the name instead of (only
- sometimes) outputting a preceding "directory " string.
-
- - The --stats output will contain file-list time-statistics if both
- sides are 2.6.4, or if the local side is 2.6.4 and the files are
- being pushed (since the stats come from the sending side).
- (Requires protocol 29 for a pull.)
-
- - The "%o" (operation) log-format escape now has a third value (besides
- "send" and "recv"): "del." (with trailing dot to make it 4 chars).
- This changes the way deletions are logged in the daemon's log file.
-
- - When the --log-format option is combined with --verbose, rsync now
- avoids outputting the name of the file twice in most circumstances.
- As long as the --log-format item does not refer to any post-transfer
- items (such as %b or %c), the --log-format message is output prior to
- the transfer, so --verbose is now the equivalent of a --log-format of
- '%n%L' (which outputs the name and any link info). If the log output
- must occur after the transfer to be complete, the only time the name
- is also output prior to the transfer is when --progress was specified
- (so that the name will precede the progress stats, and the full
- --log-format output will come after).
-
BUG FIXES:
- - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
- was only treating it as a special token in an rsync include/exclude
- file).
-
- - The combination of --verbose and --dry-run now mentions the full list
- of changes that would be output without --dry-run.
-
- - Avoid a mkdir warning when removing a directory in the destination
- that already exists in the --backup-dir.
-
- - An OS that has a binary mode for its files (such as cygwin) needed
- setmode(fd, O_BINARY) called on the temp-file we opened with
- mkstemp(). (Fix derived from the cygwin's 2.6.3 rsync package.)
-
- - Fixed a potential hang when verbosity is high, the client side is
- the sender, and the file-list is large.
-
- - Fixed a potential protocol-corrupting bug where the generator could
- merge a message from the receiver into the middle of a multiplexed
- packet of data if only part of that data had been written out to the
- socket when the message from the generator arrived.
-
- - We now check if the OS doesn't support using mknod() for creating
- FIFOs and sockets, and compile-in some compatibility code using
- mkfifo() and socket() when necessary.
-
- - Fixed an off-by-one error in the handling of --max-delete=N. Also,
- if the --max-delete limit is exceeded during a run, we now output a
- warning about this at the end of the run and exit with a new error
- code (25).
-
- - One place in the code wasn't checking if fork() failed.
-
- - The "ignore nonreadable" daemon parameter used to erroneously affect
- readable symlinks that pointed to a non-existent file.
-
- - If the OS does not have lchown() and a chown() of a symlink will
- affect the referent of a symlink (as it should), we no longer try
- to set the user and group of a symlink.
-
- - The generator now properly runs the hard-link loop and the dir-time
- rewriting loop after we're sure that the redo phase is complete.
-
- - When --backup was specified with --partial-dir=DIR, where DIR is a
- relative path, the backup code was erroneously trying to backup a
- file that was put into the partial-dir.
-
- - If a file gets resent in a single transfer and the --backup option is
- enabled along with --inplace, rsync no longer performs a duplicate
- backup (it used to overwrite the first backup with the failed file).
-
- - One call to flush_write_file() was not being checked for an error.
-
- - The --no-relative option was not being sent from the client to a
- server sender.
-
- - If an rsync daemon specified "dont compress = ..." for a file and the
- client tried to specify --compress, the libz code was not handling a
- compression level of 0 properly. This could cause a transfer failure
- if the block-size for a file was large enough (e.g. rsync might have
- exited with an error for large files).
+ - A crash bug was fixed when a daemon had its "path" set to "/", did
+ not have chroot enabled, and used some anchored excludes in the
+ config file.
- - Fixed a bug that would sometimes surface when using --compress and
- sending a file with a block-size larger than 64K (either manually
- specified, or computed due to the file being really large). Prior
- versions of rsync would sometimes fail to decompress the data
- properly, and thus the transferred file would fail its verification.
-
- - If a daemon can't open the specified log file (i.e. syslog is not
- being used), die without crashing. We also output an error about
- the failure on stderr (which will only be seen if --no-detach was
- specified) and exit with a new error code (6).
-
- - A local transfer no longer duplicates all its include/exclude options
- (since the forked process already has a copy of the exclude list,
- there's no need to send them a set of duplicates).
-
- - When --progress is specified, the output of items that the generator
- is creating (e.g. dirs, symlinks) is now integrated into the progress
- output without overlapping it. (Requires protocol 29.)
-
- - When --timeout is specified, lulls that occur in the transfer while
- the generator is doing work that does not generate socket traffic
- (looking for changed files, deleting files, doing directory-time
- touch-ups, etc.) will cause a new keep-alive packet to be sent that
- should keep the transfer going as long as the generator continues to
- make progress. (Requires protocol 29.)
-
- - The stat size of a device is not added to the total file size of the
- items in the transfer (the size might be undefined on some OSes).
-
- - Fixed a problem with refused-option messages sometimes not making it
- back to the client side when a remote --files-from was in effect and
- the daemon was the receiver.
-
- - The --compare-dest option was not updating a file that differred in
- (the preserved) attributes from the version in the compare-dest DIR.
-
- - When rsync is copying files into a write-protected directory, fixed
- the change-report output for the directory so that we don't report
- an identical directory as changed.
+ - Fixed a case where the generator might try to tweak the write
+ permissions of a read-only directory in list-only mode.
ENHANCEMENTS:
- - Rsync now supports popt's option aliases, which means that you can
- use /etc/popt and/or ~/.popt to create your own option aliases.
-
- - Added the --delete-during (--del) option which will delete files
- from the receiving side incrementally as each directory in the
- transfer is being processed. This makes it more efficient than the
- default, before-the-transfer behavior, which is now also available as
- --delete-before (and is still the default --delete-WHEN option that
- will be chosen if --delete or --delete-excluded is specified without
- a --delete-WHEN choice). All the --del* options infer --delete, so
- an rsync daemon that refuses "delete" will still refuse to allow any
- file-deleting options (including the new --remove-sent-files option).
-
- - All the --delete-WHEN options are now more memory efficient:
- Previously an duplicate set of file-list objects was created on the
- receiving side for the entire destination hierarchy. The new
- algorithm only creates one directory of objects at a time (for files
- inside the transfer).
-
- - Added the --copy-dest option, which works like --link-dest except
- that it locally copies identical files instead of hard-linking them.
-
- - Added support for specifying multiple --compare-dest, --copy-dest, or
- --link-dest options, but only of a single type. (Promoted from the
- patches dir and enhanced.) (Requires protocol 29.)
-
- - Added the --max-size option. (Promoted from the patches dir.)
-
- - The daemon-mode options are now separated from the normal rsync
- options so that they can't be mixed together. This makes it
- impossible to start a daemon that has improper default option values
- (which could cause problems when a client connects, such as hanging
- or crashing).
-
- - The --bwlimit option may now be used in combination with --daemon
- to specify both a default value for the daemon side and a value
- that cannot be exceeded by a user-specified --bwlimit option.
-
- - Added the "port" parameter to the rsyncd.conf file. (Promoted from
- the patches dir.) Also added "address". The command-line options
- take precedence over a config-file option, as expected.
-
- - In _exit_cleanup(): when we are exiting with a partially-received
- file, we now flush any data in the write-cache before closing the
- partial file.
-
- - The --inplace support was enhanced to work with --compare-dest,
- --link-dest, and (the new) --copy-dest options. (Requires protocol
- 29.)
-
- - Added the --dirs (-d) option for an easier way to copy directories
- without recursion.
-
- - Added the --list-only option, which is mainly a way for the client to
- put the server into listing mode without needing to resort to any
- internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
- for a non-recursive listing). This option is used automatically
- (behind the scenes) when a modern rsync speaks to a modern daemon,
- but may also be specified manually if you want to force the use of
- the --list-only option over a remote-shell connection.
-
- - Added the --omit-dir-times (-O) option, which will avoid updating
- the modified time for directories when --times was specified. This
- option will avoid an extra pass through the file-list at the end of
- the transfer (to tweak all the directory times), which may provide
- an appreciable speedup for a really large transfer. (Promoted from
- the patches dir.)
-
- - Added the --filter (-f) option and its helper option, -F. Filter
- rules are an extension to the existing include/exclude handling
- that also supports nested filter files as well as per-directory
- filter files (like .cvsignore, but with full filter-rule parsing).
- This new option was chosen in order to ensure that all existing
- include/exclude processing remained 100% compatible with older
- versions. Protocol 29 is needed for full filter-rule support, but
- backward-compatible rules work with earlier protocol versions.
- (Promoted from the patches dir and enhanced.)
-
- - Added the --delay-updates option that puts all updated files into
- a temporary directory (by default ".~tmp~", but settable via the
- --partial-dir=DIR option) until the end of the transfer. This
- makes the updates a little more atomic for a large transfer.
-
- - If rsync is put into the background, any output from --progress is
- reduced.
-
- - Documented the "max verbosity" setting for rsyncd.conf. (This
- setting was added a couple releases ago, but left undocumented.)
-
- - The sender and the generator now double-check the file-list index
- they are given, and refuse to try to do a file transfer on a
- non-file index (since that would indicate that something had gone
- very wrong).
-
- - Added the --itemize-changes (-i) option, which is a way to output a
- more detailed list of what files changed and in what way. The effect
- is the same as specifying a --log-format of "%i %n%L" (see both the
- rsync and rsyncd.conf manpages). Works with --dry-run too.
-
- - Added the --fuzzy (-y) option, which attempts to find a basis file
- for a file that is being created from scratch. The current algorithm
- only looks in the destination directory for the created file, but it
- does attempt to find a match based on size/mod-time (in case the file
- was renamed with no other changes) as well as based on a fuzzy
- name-matching algorithm. This option requires protocol 29 because it
- needs the new file-sorting order. (Promoted from patches dir and
- enhanced.) (Requires protocol 29.)
-
- - Added the --remove-sent-files option, which lets you move files
- between systems.
-
- - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
- enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
- literals in the rsync://HOST:PORT/PATH format.)
-
- - When rsync recurses to build the file list, it no longer keeps open
- one or more directory handles from the dir's parent dirs.
-
- - When building under windows, the default for --daemon is now to
- avoid detaching, requiring the new --detach option to force rsync
- to detach.
-
- - The --dry-run option can now be combined with either --write-batch or
- --read-batch, allowing you to run a do-nothing test command to see
- what would happen without --dry-run.
-
- - The daemon's "read only" config item now sets an internal read_only
- variable that makes extra sure that no write/delete calls on the
- read-only side can succeed.
-
- - The log-format % escapes can now have a numeric field width in
- between the % and the escape letter (e.g. "%-40n %08p").
-
- - Improved the option descriptions in the --help text.
-
- SUPPORT FILES:
-
- - Added atomic-rsync to the support dir: a perl script that will
- transfer some files using rsync, and then move the updated files into
- place all at once at the end of the transfer. Only works when
- pulling, and uses --link-dest and a parallel hierarchy of files to
- effect its update.
-
- - Added mnt-excl to the support dir: a perl script that takes the
- /proc/mounts file and translates it into a set of excludes that will
- exclude all mount points (even mapped mounts to the same disk). The
- excludes are made relative to the specified source dir and properly
- anchored.
-
- - Added savetransfer.c to the support dir: a C program that can make
- a copy of all the data that flows over the wire. This lets you test
- for data corruption (by saving the data on both the sending side and
- the receiving side) and provides one way to debug a protocol error.
-
- - Added rrsync to the support dir: this is an updated version of Joe
- Smith's restricted rsync perl script. This helps to ensure that only
- certain rsync commands can be run by an ssh invocation.
+ - Changed the outputting of "safe" filenames to use backslash-escaped
+ characters rather than '?'s. Any non-printable character is output
+ using octal (e.g. "\n" -> "\012"), and backslash is output as "\\".
INTERNAL:
- - Added better checking of the checksum-header values that come over
- the socket.
-
- - Merged a variety of file-deleting functions into a single function so
- that it is easier to maintain.
-
- - Improved the type of some variables (particularly blocksize vars) for
- consistency and proper size.
-
- - Got rid of the uint64 type (which we didn't need).
-
- - Use a slightly more compatible set of core #include directives.
-
- - Defined int32 in a way that ensures that the build dies if we can't
- find a variable with at least 32 bits.
-
- PROTOCOL DIFFERENCES FOR VERSION 29:
-
- - A 16-bit flag-word is transmitted after every file-list index. This
- indicates what is changing between the sender and the receiver. The
- generator now transmits an index and a flag-word to indicate when
- dirs and symlinks have changed (instead of producing a message),
- which makes the outputting of the information more consistent and
- less prone to screen corruption (because the local receiver/sender is
- now outputting all the file-change info messages).
-
- - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
- in the flag-word and the name of the file that was linked immediately
- follows in vstring format (see below).
-
- - If a file is being transferred with an alternate-basis file, the
- ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
- byte follows, indicating what type of basis file was chosen. If that
- indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
- is set in the flag-word and the name of the match in vstring format
- follows the basis byte. A vstring is a variable length string that
- has its size written prior to the string, and no terminating null.
- If the string is from 1-127 bytes, the length is a single byte. If
- it is from 128-32767 bytes, the length is written as ((len >> 8) |
- 0x80) followed by (len % 0x100).
-
- - The sending of exclude names is done using filter-rule syntax. This
- means that all names have a prefixed rule indicator, even excludes
- (which used to be sent as a bare pattern, when possible). The -C
- option will include the per-dir .cvsignore merge file in the list of
- filter rules so it is positioned correctly (unlike in some older
- transfer scenarios).
-
- - Rsync sorts the filename list in a different way: it sorts the subdir
- names after the non-subdir names for each dir's contents, and it
- always puts a dir's contents immediately after the dir's name in the
- list. (Previously an item named "foo.txt" would sort in between
- directory "foo/" and "foo/bar".)
-
- - When talking to a protocol 29 rsync daemon, a list-only request
- is able to note this before the options are sent over the wire and
- the new --list-only option is included in the options.
-
- - When the --stats bytes are sent over the wire (or stored in a batch),
- they now include two elapsed-time values: one for how long it took to
- build the file-list, and one for how long it took to send it over the
- wire (each expressed in thousandths of a second).
-
- - When --delete-excluded is specified with some filter rules (AKA
- excludes), a client sender will now initiate a send of the rules to
- the receiver (older protocols used to omit the sending of excludes in
- this situation since there were no receiver-specific rules that
- survived --delete-excluded back then). Note that, as with all the
- filter-list sending, only items that are significant to the other
- side will actually be sent over the wire, so the filter-rule list
- that is sent in this scenario is often empty.
-
- - An index equal to the file-list count is sent as a keep-alive packet
- from the generator to the sender, which then forwards it on to the
- receiver. This normally invalid index is only a valid keep-alive
- packet if the 16-bit flag-word that follows it contains a single bit
- (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
-
- - A protocol-29 batch file includes a bit for the setting of the --dirs
- option and for the setting of the --compress option. Also, the shell
- script created by --write-batch will use the --filter option instead
- of --exclude-from to capture any filter rules.
+ - Rsync now calls setlocale(LC_CTYPE, "").
BUILD CHANGES:
- - Handle an operating system that use mkdev() in place of makedev().
-
- - Improved configure to better handle cross-compiling.
+ - You can use --disable-locale to turn off any use of setlocale().
